AWeber allows you to set up some great automailers as well. You can set these up to promote affiliate products over time at set intervals. So you can have many time delayed promotional pitches mixed in with daily RSS feeds, weekly newsletters, insider tips, or anything else you can imagine. After you build your subscriber base, you can continue to have many more oppurtunities to convert sales. Best thing is you can pre-set when certain mailers go out with AWeber's automailers. The oppurtunities to bring your readers together within your mailing lists are only available, if you get an email marketing campaign underway.

AWeber is the best bang for your buck as it is only $19 a month and the first month is only $1 to try this great program out.
